I agree about the USB thumb drives - I've never needed administrator
privileges to use USB drives, so something else is at work here.
As to the printers, if they need to install new printers (not an
unusual thing to need to do when taking the computer to a new
environment), they are prevented from installing new drivers if they
do not have administrator privileges.
Fortunately, this can be changed by setting a group policy that allows
signed drivers of a particular driver class to be installed by
non-administrators. To do this, launch Group Policy Editor
(gpedit.msc), and under Local Computer Policy navigate to Computer
Configuration, Administrative Templates, System, Driver Installation.
Double-click "Allow non-administrators to install drivers for these
device setup classes," and set the policy to Enabled. Click the Show
button to enter the device classes. Click Add and enter a value of
{4d36e979-e325-11ce-bfc1-08002be10318} and click OK. Click OK to all
dialog boxes, then close the group policy editor.
For Home versions of Vista, you have to edit the registry since they
don't include the group policy editor. Save the following as a .reg
file and merge it (requires administrator permissions, of course).
Lines that do not start with two spaces have been line wrapped and
will need to be re-assembled:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Win dows\DriverInstall\Restrictions\AllowUserDeviceCla sses]
"1"="{4d36e979-e325-11ce-bfc1-08002be10318}"
Both approaches can be used for other device classes, see
http://msdn2.microsoft.com/en-us/library/ms791134.aspx for a list.
Remember, this only works for signed drivers. Also, the drivers need
to be extracted to a location you have access to - that is, the .inf
and other required files need to be stored somewhere, and you won't be
able to run an exe file to extract or install them on the Vista PC
since that requires administrator privileges as well...
